Luxembourg History
The language of Luxembourg is Luxembourgish, a blend of Dutch, old German, and Frankish elements. The official language of the civil service, law, and parliament is French, although criminal and legal debates are conducted partly in Luxembourgish and police case files are recorded in German. German is the primary language of the press. French and German are taught in the schools, with German spoken mainly at the primary level and French at the secondary level.

June 9, 1815, after 400 years of domination by various European nations, Luxembourg was made a grand duchy by the Congress of Vienna. It was granted political autonomy in 1838 under King William I of the Netherlands, who also was the Grand Duke of Luxembourg. The country considers 1835 to be its year of independence. In 1867, Luxembourg was recognized as independent and guaranteed perpetual neutrality. After being occupied by Germany in both World Wars, however, Luxembourg abandoned neutrality and became a charter member of the North Atlantic Treaty Organization (NATO) in 1949.

The present sovereign, Grand Duke Henri, succeeded his father, Grand Duke Jean on October 7, 2000. Grand Duke Jean announced his decision to abdicate in December 1999, after a 35 year reign.
